I would just delete the image file from the phone and then run the download of the image again.

The first time I ran the downloader, I had to go out so cancelled it. When I ran it again, it said it was already downloaded (despite not completing) and that it was unpacking it... I knew it would fail, so started again.

Works an absolute treat, although I didn't get the Open Office icon until the package was updated over the past week or so...
